The feature of surface electromyography signal and the mechanism of wavelet analysis characteristic generated from massage technique were mainly researched, and then the relevant eigenvalues of the wavelet theory were extracted from the data of kneading method. The results showed that after analyzing the wavelet characteristics between the experts and the beginners, we could effectively distinguish...
The style of study has a direct impact on the quality of school's education; and education quality directly affects the survival, development problem. Construction of good style of study is the universities' long-term and arduous task. Construction of good style of study is inseparable from the scientific and reasonable evaluation of the style of study. Academic atmosphere evaluation reflects the...
Owing to the industry characteristics of civil servants which have special requirements on spirit of service and devotion, exploring the status quo and relationship of its workplace spirituality and organizational citizenship behavior makes a big difference to improve the capability and efficiency of government services. Through the survey of 468 civil servants in Beijing, the study found that the...
Ascertainable clustering number is one of the vital problems of spectral clustering. To solve this problem, a spectral clustering algorithm automatically determining the clustering number is proposed. By mapping the sample point of the data set into feature space, the orthogonal positional relationship of sample points between different clusters in the feature space can be determined. Based on the...
In this paper, we consider group consensus problem with switching topology by giving a kind of new protocol in which communication graph weights are all nonnegative. This is also consistent with classic protocols. The sufficient conditions which group consensus under this kind of protocols can reach for both single and second order multi-agent system are obtained. Finally, numerical examples are given...
The micro solder joints serve as mechanical supporting and electrical connections in assembly of WLCSP devices on board-level. As the requirements of miniaturization, weight reduction in modern electronic devices, the dimension of solder joints is decreasing as small as 100um due to higher-density connections and smaller chip size. The integration of the solder joints is one of the key problems related...
This study extends research on factors that contribute to abusive supervision, one form of nonphysical aggression, and the results of such abuse on subordinates' performance. We utilize research on personal values theory and general aggression model to formulate our hypotheses. Results from 206 matched leader-subordinate dyads support the idea that leader's self-transcendence values were positively...
This paper discusses the contract model for a three-stage service supply chain which consists of a service demander, a service integration supplier and service suppliers with a contract service supplier and some temporary suppliers. It is proposed a joint contract of compensation and revenue sharing for the mathematical model. Our contribution in the case of meeting the uncertain demands of market...
Communication is the life-blood of a project, whether permanent or temporary. It is essential for project stakeholders to identify and evaluate communication efficiency, which can reveal the relationships of responsibilities, powers and interests among stakeholders. This paper explores a new evaluation model of project communication based on cloud gravity centre theory. To assess project communication...
This paper proposes to apply Bayesian principle to clustering matting components in spectral matting. Spectral matting is a useful and effective technique for digital image matting. A crucial issue of spectral matting is how to cluster the computed matting components, which compose the final alpha matte. In this paper, a new clustering strategy based on Bayesian decision theory is proposed to solve...
Based on the development and utilization of the Tertiary groundwater in southern Xialiaohe aquifer, the development pattern of up Tertiary groundwater is established, the primary evaluating indicators include the extraction coefficient of groundwater, the over extraction coefficient of groundwater, the aquifer thickness, the chloride ion concentration, groundwater level, a new fuzzy identification...
Statistics of body composition was measured by In body 3.0, use mathematical statistics method to select the related index of influencing body composition in the college P.E. major students, The result shows that the main index of influencing body composition in the college P.E. major students are control of fat, body density, muscle, extra cellular fluid, TP total protein, bone total protein, lean...
Okadaic acid (OA), a key diarrheic shellfish poisoning (DSP) toxin will possibly arouses DSP symptoms by consuming the contaminated shellfish. The DSP toxins are stable at high temperatures, and long-term DSP toxicity is carcinogenic. Therefore a fast and reliable analytical method for the detection of OA and analogues in shellfish is worth developing. In this paper, a direct competitive ELISA (dcELISA)...
In recent years, AADL (Architecture Analysis and Design Language) is used widely in the design of embedded software. There is a growing concern about quality and reliability of AADL design model and codes made from model. In this paper, we propose a testing method that test cases can be generated based on AADL system component modes to support embedded software testing. The information of AADL system...
Time/cost trade-offs problems in the project management is the important role. The project scheduling with the traditional approach does not consider the difference execution time on the unit period for all activities of project. In this paper, firstly, it presents an introduction of the problem description of time-switch constraints. Then, the project scheduling with time-switch constraints under...
This paper constructs a comprehensive classification standard which constituted by five variables reflecting the migrant workers' actual migration behaviors. Migrant workers' migration patterns are divided into two categories according to their actual migration behaviors: temporary migration and permanent migration. Then, compare the major economic indicators and test the differences between categories...
dl-Gylcerol monoester of pivalic acid was synthesized by alcoholysis reaction of pivalyl chloride with acetone ketal of glycerine. The effect of molar ratio, reaction time, reaction temperature and catalyst dosage on the yield was investigated. The product structure was characterized by IR and 1HNMR. Results indicated that yield of dl-gylcerol monoester of pivalic acid reached 75.5% at 25°C and 6h...
Based on the method of image edge detection on gray weighted absolute correlation degree of Gray System Theory, a novel method for image edge detection is presented based on grey weighted absolute correlation degree and the classical Prewitt edge detection operator. The method is to take the Prewitt operator as reference sequence, and calculate the grey weighted absolute correlation degree of the...
The industry-university-research cooperation system is a complex system, which has self-organization trait once the system is established that is same to other dissipative structure systems. The cooperation system evolution process includes three stages and has a complex structure. The industry-university-research cooperation system is a system includes many subsystems. The stabilization and mutual...
Taking the shortest distance as the performance index and the 6-DOF fruit picking robot as the research object, the various points of path that robot passed are planned with the genetic algorithm, considering the joint velocity, acceleration and acceleration restriction. The results which are simulated with robotics toolbox of matlab indicate that the method of robot path planning not only ensures...
